Low-cost graphene-based biosensor chip detects DNA mutations in real time

One of the most common indicators of many diseases and cancer in blood is the presence of a genetic mutation known as a single nucleotide polymorphism (SNP). Unfortunately, to date such tests for SNPs are slow, cumbersome and – above all – expensive. Now a team of researchers from the University of California, San Diego (UCSD) have developed a new graphene-based sensor that promises to deliver test results easily, in real time, and inexpensively. The researchers believe this could be a breakthrough in the early detection and screening for many life-threatening illnesses.Read More

Lelo gives condom design hex appeal

There are times when a 98 percent success rate is acceptable, but in the world of condoms that last two percent is worth striving for. Lelo, a notable purveyor of sex toys, wants to make (adult) playtime safer and more fun with a new, hexagon-heavy condom design endorsed by none other than Charlie Sheen.Read More

Reusable microbots make meal of toxic metals

Researchers have developed a tube-shaped microbot that offers a cheaper and more effective way of removing heavy metals than previous methods. The self-propelled microbots use an outer layer of graphene that binds to lead ions it comes in contact with. The scientists found that they can remove 95 percent of lead from polluted water in one hour, and once they have a full payload, they can be cleaned and reused multiple times.Read More

For better bike tires, just add graphene

When it comes to high-end bicycle tires, buyers generally have to choose between light, fast ones and grippier, more durable models. According to Italian tire manufacturer Vittoria, however, that's no longer the case – at least, not with the company's new Graphene Plus rubber.Read More

Beating graphene at its own game

Over the last few years, you'd struggle to have not at least heard mention of an extremely strong, electrically- and thermally-conductive, one-atom thick material called graphene. But now, researchers at the University of Kentucky are looking to create a new material that might just boast even more impressive and useful attributes.Read More

Chance discovery puts graphene electronics closer to mass production

We've heard plenty on the wonderful properties of graphene, but the supermaterial par excellence still hasn't found its way to commercial products because it is too delicate for real-world conditions. Now, in a lucky and perhaps game-changing discovery, scientists at the Brookhaven National Laboratory (BNL) have found that placing graphene on top of common industrial-grade glass is a cheap and effective way of making it resilient and tunable, paving the way for the production of graphene-based electronics on a large scale.Read More

Liquid-like graphene could be the key to understanding black holes

Researchers at Harvard University and Raytheon BBN Technology have discovered that the charged particles inside high-purity graphene behave as a fluid with relativistic properties. This find could lead to devices that efficiently convert heat into electricity, as well as graphene-based chips that can accurately model the behavior of faraway celestial objects like supernovas and black holes.Read More

Graphene successfully interfaced with neurons in the brain

Scientists have long been on a quest to find a way to implant electrodes that interface with neurons into the human brain. If successful, the idea could have huge implications for the treatment of Parkinson's disease and other neurological disorders. Last month, a team of researchers from Italy and the UK made a huge step forward by showing that the world's favorite wonder-material, graphene, can successfully interface with neurons.Read More
